Samir Nasri has impressed since joining Arsenal from French club Marseille last summer.

The France international will miss the start of the upcoming English Premier League season, and is expected to be on the sidelines for up to three months.

The 22-year-old winger fractured a right fibula during a morning training session at the London club's pre-season camp in Austria.

He made a strong impact in his first season at the Emirates Stadium following his switch from Marseille as he took his chance in the absence of the injured Tomas Rosicky.

However, the Czech international is now almost ready to return to regular first-team contention, having played his first game for the club in 18 months against lower-league outfit Barnet last weekend.

Arsenal manager Arsene Wenger had earlier called on the club's fans to support his existing playing squad ahead of the new campaign, following the $41 million departure of Togo striker Emmanuel Adebayor to EPL rivals Manchester City.

"The message is to trust the players that we have," the Frenchman told Arsenal's official Web site.
